"In a study published in Nature Communications, the researchers reveal an elegant molecular mechanism that acts like a GPS coordinate system for regenerating cells… the puzzle was how the cells in the regenerating limb-stump controlled their levels so precisely to know exactly where they were on the axis from shoulder to hand.”
The Nature paper:
How it could work in a future: they pre-grow limbs in labs for a few months/yearst, then when somebody needs it, they attach one that matches closely. After that, you get the treatment and the limb continues growing until it reaches the size needed.
Imagine running around with a child arm for a year or so.
Compared to no arm for the rest of my life, being called “baby-hand” for a year seems like a small price to pay.
True. It would probably be funny.
Isn’t that a Michael Bay film?
